Specification of Letters Patent.

Patented June 80, 1908.

Application filed May 29, 1906. Serial No. 319,314.

To all rwhom it may concern:

Be it known that we, JAPHUs GEORGE, of Wilcox, in the county of Elk andState of Pennsylvania, and CHRISTOPHER M. SHORTLE, of Bernhards Bay, inthe county of Oswego and State of New York, have invented certain newand useful Improvements in Apparatus for Manufacturing Wire- Glass; andwe do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use Y the same.

Our invention relates to im roved ap aratus for manufacturing wiregfass, the o ject of the invention being to cast the wire glass in moldsand finish the glass with both faces polished, a thing im ossible withmechanism eretofore employe and the invention consists in certain novelfeatures of construction and combinations and arrangements ofparts aswill be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings, Fi ures 1, 2, 3 and 4 'are views in crosssection il ustrating our im rovements in the several stages of the manuacture of wire glass. Fig. 5 is a view inflongitudinal section, Fig. 6is an end view of the moId. Fig. 7 is an enlarged sectional view showingoperation of polisher and Figs. 8, 9 and 10 are views of a modification.

1 represents a supporting frame having half-bearings 2 to ysupport thetrunnions of the mold sections, as will hereinafter appear.

3 represents a pan or mold section w ich is employed as the first stepin making wire glass. This pan 3 is provided with semi-cyindricaltrunnions 4 restingin bearings 2 and having half s uare out'er ends 5.This pan is securedin a ori'zontal position by hooks or other suitabledevices, is strengthened by webs 7 and provided in its bottom with pins8 to revent movement of the wire netting 9 which is located in thebottom of the an 3, as shown in Fig. 1. The molten glass 1s then pouredinto the pan to fill the same and the polisher 10 is then used to polishthe surface of the glass in the pan. This polisher comprises a barhaving a rounded lower face, and made on its upper face with grooves tore vceive tallow or other like material, which due to the heat from theglass will melt and flow through the perforations 11 in the bar downonto the glass to lubricate the surface and insure a good polish The bar10 is mounted `on wheeled trucks 13, the latter movable in groovedtracks 15 at the sides of the frame. Ooiled springs 15 are located onthe, rods 12 below the bar 10 to yieldingly press the bar upwardlyagainst adjusting nuts 16 on the rods.

The polisher 10 is reciprocated over the glass by a drum 17 supported atthe center of the frame and provided with an operating crank 18. Ropesor chains 19 secured to the wheeled trucks 13 are passed around pulleys2O at the ends' of the tracks and wound around drum 17 so that byturning the latter the polisher can be moved back and forth over theglass. j

The next step in the operation is to place the mold section 21 on thetop of pan 3. This mold section 21 has a perfectly smooth lower face torest against the glass and is provided with semi-cyzlindrical trunnions22 and half square ends to fit against trunnions and half square ends 5,so that when crank arms 23 having angular o enings are placed on theangular ends of the alftrunnions, the mold sections will be lockedtogether and can be turned over. When in this position, pan 3 can beremoved leaving the glass with, wire side u on the smooth surface ofmold section l 21.

en in this position, an oblongv open frame or mold section 24 is locatedon mold section 21 as shown in Fig. 3 and is just twice the thickness ofpan 3 and provides a receptacle for glass which permits an equalquantity of lass to be poured on to of the wire as thatelow the same.This ame or I'nold section 24v is made with aflan e 25 and at its endson upright screw-threaded rods 12 pins 26 to exactly position it on mosection 21 and when positionedI as shown 1n Fig. 3 forms a erfectlytight rece tacle for the W ien the frame 24 is led with glass, the nuts16 are adjusted to ermit the olisher 10 to move over the su ace ofthe gass in frame 24 and olish the same. After the glass is polished t eframe 24 can be removed and the wire glass, polished on both faces willrest on the smooth surface of the mold section 21 and can be disposed ofas found most desirable. j

All the mold sections "are provided with openings' for the reception ofhooks on cranes or other devices for handling them and we do not ofcourse restrict ourse ves to any particular means for the purposes.

In the modification shown in Figs. 8, 9, and

10, the pans 27 are constructed exactly alike and the wire netting isplaced in the bottom second pan.

of one pan and glass poured thereon and the `surface polished. The otherpan 27 is then held on the glass filled pan by means of the `lockedtrunnions at theend and the 'pans turned over to Abring thewire side upin the A band or angular ring 28 is then located on the second pan andthe glass oured therein and polished. The band 28 has the saine depthas`^"the ans so that an equal thickness of glass Wi be formed at bothsides of the Wire nettin and as above explained both, faces ofthe g asswill be pol- ,l v

'A greats many slight changes might be made in the general form andarrangement of the parts described without Adeparting from our inventionand hence we do not restrict ourselves to the recise details set forthbut consider ourse ves at liberty to make such slight changes andalterations as fairly fall within the spirit and scope of our4 polisheron each face of the glass.
